I don't quite get the regex in 5474-1 shown below. The '+' I think I get; if the data is a GET or a POST with enctype=application/x-www-form-urlencoded then spaces are encoded as +. But the regex also appears to be looking for a literal '%' and then '20'. Why for? If the request is "multipart/form-data" it will have a space character in the data (which has a hex value of \x20 but that's not what the regex is looking for).
